I may hand over to men their fortunes, now their understanding is emancipated and come as it were of age; whence there cannot but follow an improvement in man's estate and an enlargement of his power over nature. For man by the fall fell at the same time from his state of innocency and from his dominion over creation…
The doctrine of those who have denied that certainty could be attained at all has some agreement with my way of proceeding at the first setting out; but they end in being infinitely separated and opposed. For the holders of that doctrine assert simply that nothing can be known. I also assert that not much can be known…
Man, being the servant and interpreter of Nature, can do and understand so much and so much only as he has observed in fact or in thought of the course of nature. Beyond this he neither knows anything nor can do anything.
I have on my own part made it my care and study that the things which I shall propound should not only be true, but should also be presented to men's minds, how strangely soever preoccupied and obstructed, in a manner not harsh or unpleasant. It is but reasonable, however (especially in so great a restoration of…
Metaphysically speaking, no one paradigm is innately any better than any other. A universe that began at 9 a.m. on October 10, 4004 B.C. (which was official back in the seventeenth century) is intrinsically no less valuable for those who live by a belief in it than is our present uncertain universe, perhaps built like…
Anthropocentrism isn’t just a faulty value system, but also a faulty way of understanding the world. Modern science has shown this, displacing human beings from the center of the universe, opening up immense vistas of space and time, telling a story of life in which chance, not destiny, has raised an unusual primate…
That we need a planetary ethic is so obvious that I need but list a few key words: climate, ethnic cleansing, fossil fuels, habitat preservation, human rights, hunger, infectious disease, nuclear weapons, oceans, ozone layer, pollution, population. Our global conversations on these topics are, by definition…
I have a tolerance for ambiguity. It's clear to me that there's some questions that humans don't have the answers to and what arrogance to imagine we have answers to all questions. Science is sometimes, I know, attacked for supposed arogance, but I think it's the most humble occupation and discipline around. Because…
His metaphysics, as ingenious and new as his physics, had approximately the same fate; and it is with approximately the same reasons that we can justify it. For such is today the fortune of this great man that after having had countless followers he is practically reduced to a few apologists. He was without doubt…
It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.
Again, the reason science works so well is partly that built-in error-correcting machinery. There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths. That openness to new ideas, combined with the most rigorous, sceptical scrutiny of all ideas, sifts the wheat…
the hard but just rule is that if the ideas don't work, you must throw them away. Don't waste neurons on what doesn't work. Devote those neurons to new ideas that better explain the data. The British physicist Michael Faraday warned of the powerful temptation to seek for such evidence and appearances as are in the…
One of the great commandments of science is, 'Mistrust arguments from authority'. (Scientists, being primates, and thus given to dominance hierarchies, of course do not always follow this commandment.) Too many such arguments have proved too painfully wrong. Authorities must prove their contentions like everybody…
...science is more than a body of knowledge; it is a way of thinking. I have a foreboding of an America in my children's or grandchildren's time - when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome…
Perhaps the sharpest distinction between science and pseudoscience is that science has a far keener appreciation of human imperfections and fallibility than does pseudoscience (or 'inerrant' revelation). If we resolutely refuse to acknowledge where we are liable to fall into error, then we can confidently expect that…
It was from Kuiper that I first got a feeling for what is called a back-of-the-envelope calculation: a possible explanation to a problem occurs to you, you pull out an old envelope, appeal to your knowledge of fundamental physics, scribble a few approximate equations on the envelope, substitute in likely numerical…
There have always been two ways of looking for truth. One is to find concepts which are beyond challenge, because they are held by faith or by authority or the conviction that they are self-evident. This is the mystic submission to truth which the East has chosen, and which dominated the axiomatic thought of the…
I believe in the great discovery. I believe in the man who will make the discovery. I believe in the fear of the man who will make the discovery. I believe in his face going white, His queasiness, his upper lip drenched in cold sweat. I believe in the burning of his notes, burning them into ashes, burning them to the…
We want to stand upon our own feet and look fair and square at the world -- its good facts, its bad facts, its beauties, and its ugliness; see the world as it is and be not afraid of it. Conquer the world by intelligence and not merely by being slavishly subdued by the terror that comes from it... A good world needs…
We now find that a great many things we thought were natural laws are really human conventions. You know that even in the remotest depths of stellar space there are still three feet to a yard. That is, no doubt, a very remarkable fact, but you would hardly call it a law of nature. And a great many things that have…
